Beginners 51 single-chip microcomputer and the great spirit to guide the following this figure progr-CodePudding

Here as I have to write code (led only after the simulation running water, and cannot achieve button control led and water) :

# include "reg52. H"//this file defines the MCU some special function register
# include//to use move function, so join the header file

typedef unsigned int u16;//to statement defines the data type
Typedef unsigned char u8;

# define led P1
Sbit k1=p3 ^ 0;
U8 a;

Void delay (under-16 I)
{
While (I -);
}

Void main ()
{
u8 i;
Led=0 xfe;
Delay (50000);//about 450 ms delay
While (1)
{
If (k1==0)
{
delay(1000);
If (k1==0)
{
A=~ a;
}
}
If (a==0)
{
for(i=0; i<7. I++)
{
Led, led=_crol_ (1);
Delay (50000);//about 450 ms delay
}
}
If (a==1)
{
for(i=0; i<7. I++)
{
Led, led=_cror_ (1);
Delay (50000);//about 450 ms delay
}
}
}
}

1. U8 a; A, not initialized.
2. If a=0, then a=~ a; After a=255,

Can you teach me how to change? thank you

CodePudding user response:

U8 a=0;//initialize

If (k1==0)
{
A=! A;//use logical
}
